Officers do not set the dog on the agitated man. But moments later, Hall appears to take a few steps away from the officers, at which point they open fire on him with a barrage of dozens of bullets. Hall falls to the ground dead.

The Huffington Post reports that all six officers involved in the shooting were placed on administrative leave pending the outcome of an investigation.

Hall's death marked the second police-related killing in the city of 51,000 this year. In March, a Michigan State Police trooper was shot in the neck and arm by a passenger in a car stopped in the city. The trooper returned fire, killing the assailant, 24-year-old Keontae Amerson.

The Michigan State Police is investigating Hall's killing.

Matthew Frey, a Republican running for Saginaw County prosecutor, told the Saginaw News that he will "review the case again" if the killing is ruled justifiable and he is elected this November.

"I am extremely upset over what I saw," Frey said.

Saginaw Police Chief Gerald Cliff told CNN that Hall was "known to be an assaultive person" who had a "long history" of conflict with local and county law enforcement.

But Hall's mother questioned why the six officers acted the way they did.

"I'm stunned that six human beings would stand in front of one human being and fire 46 shots," Jewell Hall told CNN. "I just don't understand that. It's a lot of pain in that because it only takes one shot, so the question is why?"
